As many impactors as the moon and mars combined have struck the earth are 35,400. Since the deposition process is happening everywhere across the planet
a) In the past 600 million years, the Moon has been struck by about 60 impactors, compared to about 43,000 for Mars.
Therefore, if we divide the size of Washington by the size of the hit, we get
177000 km² ÷ 5 km = 35,400.
b). However, there are no impact craters that are 5 km wide because the deposition process is ongoing everywhere over the earth. The erosional material that fills the craters causes them to shrink in size until they are no wider than 5 kilometers.
A deposition is a geological process that involves the addition of soil, rocks, and sediments to a landform or landmass. Transported by wind, ice, water, and gravity, previously weathered surface material is deposited when enough kinetic energy in the fluid is lost, forming layers of sediment.
The null-point hypothesis states that deposition occurs when sediment transportation-related forces are no longer strong enough to overcome gravity and friction-related factors, which provide resistance to motion. The deposition also covers the accumulation of sediment brought on by chemical or organic processes.

A bat flies toward a wall, emitting a steady sound of frequency 1. 70 khz. This bat hears its own sound plus the sound reflected by the wall. How fast should the bat fly in order to hear a beat frequency of 8. 00 hz?.
The bat should fly about 0.8065 m/s in order to hear a beat frequency of 8 Hz.
The shift in a wave's frequency caused by an observer moving away from the wave source is known as the Doppler effect or Doppler shift. The equation for this is given by,
[tex]f=\frac{v \pm v_0}{v\mp v_s}f_s[/tex]
where f is the observed frequency, v is the speed or velocity of the sound waves, v₀ is observer velocity ("+" if it's towards and "-" if it's away from the source), vs is source velocity("-" if it's towards and "+" if it's away from the observer), and fs is the actual frequency of the sound waves.
The velocity of sound waves in the air is 344 m/s, v₀ is zero for the incident, v is the source velocity towards the wall, and fs is 1700 Hz.
Then, the incident frequency is given by,
[tex]f_{incidence}=\frac{344-0}{344-v}\times f_s[/tex]
The wall is stationary, therefore, f(incidence)=f(reflected). Then, the new frequency the bat hears is,
[tex]\begin{aligned}f_{new}&=\frac{344+v}{344}\times f_{reflected}\\&=\frac{344+v}{344}\times \frac{344-0}{344-v}\times f_s\\&=\frac{344+v}{344-v} \times f_s\end{aligned}[/tex]
To hear a beat frequency of 8 Hz, the velocity of the bat should be,
[tex]\begin{aligned}f_{new}-f_s&=8\\\left(\frac{344+v}{344-v} \right)f_s-f_s&=8\\\frac{344+v}{344-v}-1&=\frac{8}{f_s}\\\frac{344+v-344+v}{344-v}&=\frac{8}{1700}\\2v&=0.0047(344-v)\\2v&=1.6168-0.0047v\\2.0047v&=1.6168\\v&=\mathrm{0.8065\;m/s}\end{aligned}[/tex]

Explanation:
the threshold of hearing is defined as the minimum discernible intensity of the sound. it is approximately 10−12w/m2 . find the distance d from the car at which the sound from the stereo can still be discerned. assume that the windows are rolled down and that each speaker actually produces 0.06 w of sound, as suggested in the last follow-up comment.
Distance d from the car at which the sound from the stereo can still be discerned are= 97720.5 m
Briefly:-The link between sound intensity at a distance and distance is (power of sound at source)/ (surface area of the wall of an imaginary sphere at the distance in question)
I = P/4πd²
Assuming the car has 2 speakers,
P = 0.06 W × 2 = 0.12 W

When a car of mass 1200 kg is moving with a velocity of 15m s?
The car will move to distance 225 m.
The car is slowing in speed due to friction force and eventually stops. Friction force is force between road and tire of car. Friction force always opposes the motion of an object.
Coefficient of kinetic friction μk is the ratio of the friction force to the normal force experienced by a moving body.
Friction force is,
f = mu N
f =friction force
mu =coefficient of friction
N =normal force
So, f = 0.5×1200 N
acceleration, a = -0.5×1200/1200= 1200 m/[tex]s^{2}[/tex]

Work is defined as the force applied over a distance. The force must be applied in the direction of motion. Work is the way that energy is added to an object or system. Because of conservation of energy, you can only get as much energy as you put in. Simple machines may reduce the force needed to complete a task, but cannot reduce the amount of work needed. The work output with a simple machine can never be greater than the work input.

Their final temperature is 303.2K
Container1
Mass m1 = 57.9 kg
temperature = 237k
Container 2
Mass m2 = 26.7 kg
temperature = 159 k
Heat gained by container 1 to reach equilibrium = heat lost by container 2 to reach equilibrium.
m1sΔT = m2sΔT
57.9 × S × (T - 237) = 26.7 × S × (T - 159)

A = final amount
Ao = Initial amount
t = time period
h = half-life
Parameters given in the problem:
h = 13 minutes
Ao = 400 grams

The pulley is initially at rest are:
a) The angular acceleration is 0 rad/s^2.
b) The angular speed is 0 rad/s.
Initially, the acceleration of the pulley is zero. As the pulley starts to move, the acceleration increases until it reaches its maximum value, which is determined by the magnitude of the force applied to it. As the pulley continues to move, the acceleration gradually decreases until it reaches zero again as the pulley comes to rest.
Angular acceleration is the rate at which the angular velocity of an object changes over time. It is usually expressed in terms of radians per second squared (rad/s2). Angular acceleration is caused by a torque being applied to an object and can be used to predict the angular velocity of a spinning object. Angular acceleration is a vector quantity, meaning it has both magnitude and direction.
Angular speed is the rate at which an object rotates or revolves around an axis. It is measured in terms of angle per unit of time and is usually expressed in radians per second (rad/s) or revolutions per second (rpm). Angular speed is related to linear speed, which is the distance traveled per unit of time.

What is the wavelength of the green light with a frequency of 5.71 x 1014 Hz?
The wavelength of green light is 5.39 x 10⁻⁷m.
Electric powered discipline lines originate on fantastic prices and terminate on terrible fees. the electric subject is defined because the force in keeping with unit price on a check charge, and moreover, the electricity of the pressure is related to the electrical regular, additionally known as the free area permittivity.
From Maxwell’s 1st equation we have a tendency to collect a special form of Coulomb’s regulation called Gauss’s regulation for strength.
Maxwell created fundamental contributions to the development of bodily technological know-how.
He turned into also the founder of the kinetic idea of gases.
This concept supplied the new difficulty of implemented arithmetic, and physics, linking thermodynamics and mechanics, and is still widely used as a model for rarefied gases and plasmas.
The equation, E=hf, is referred to as the Planck-Einstein relation. The letter h is named after Planck, as Planck’s consistent. energy (E) is associated with this constant h, and to the frequency (f) of the electromagnetic wave.
E=hc/y
y=c/v
y=3 x10⁸/5.71 x 10¹⁴=5.39 x 10⁻⁷m

What are infrared used for in the electromagnetic spectrum?
Infrared from the electromagnetic spectrum is used in various applications.
Infrared radiation is an electromagnetic radiation with wavelengths longer than those of visible light. It is undetectable by the human eye. Infrared waves are referred to as thermal waves. This is because they have a heat inducing property.
The following are the areas of use of infrared waves:
Infrared waves are used in the medical field as infrared saunas are used to treat high blood pressure and rheumatoid arthritis. Infrared radiation is considered one of the safest methods of physiotherapy.
Industries which concentrate on manufacturing processes such as forming of plastics, curing of coatings, plastic welding, etc use infrared heaters in place of contact heating and convection ovens.
Infrared radiation is used in optical fibre communication.
